The paper surveys the current status of the models for representing, manipulating and
analyzing dimensioning and tolerancing data behind the major computer-aided tolerancing …

Dimensioning and tolerancing are inter-related tasks; the validity of the tolerance
representation model is dependent on the dimension model. Validation of tolerances is …

A computer aided tolerance analysis tool is presented that assists the designer in evaluating
worst case quality of assembly after tolerances have been specified. In tolerance analysis …

In current tolerancing practice, designers have to manually specify tolerances: either on a
drawing or in a CAD system. Different designers will possibly arrive at different tolerance …

When designing a mechanical product, how to determine its assembly tolerance
specifications (ATS) and tolerance zone types (TZT) is a complex design problem, in which …

The paper discusses the current status of and research behind some of the major computer
aided tolerancing (CAT) systems that are now commercially available. The focus is directed …

The functional tolerancing process for complex mechanisms needs the study of the behavior
of mechanical joints. The use of the Computer-Aided Design system helps in carrying out …

In modern manufacturing engineering, tolerance synthesis is important because it directly
effects product quality and manufacturing cost. This paper introduces a new method for …

In this paper, interactive “constraint based feature definition” is used to drive both feature
based design and feature recognition. At present, hardly any feature based CAD or CAPP …

Under the new geometric product specification (GPS), a two-dimensional chain cannot
completely guarantee quality of the product. To optimize the allocation of three-dimensional …
